Title; Feeding off their unhappiness

Drop
        drop
               drop
Bring your silver lined buckets
Catch and gather
Tears for collectors

Clink
        Clink
                 Clink
What's your preference
Sadness so valuable
Happiness now obsolete

Joy
    Joy
       Joy
Your contentment rising high
Filling your void
Empty buckets make you cry

Silence
            Silence
                        Silence
Too dry a day today
Happiness a comeback
Fill their buckets
Your tears of hate
